Good news Merry Marvel fans, Activision's Marvel: Ultimate Alliance is getting the Hulk in April. Today, Activision announced plans to release its first expansion pack for last year's well-received Marvel RPG.

Marvel: Ultimate Heroes and Villains expansion adds eight new playable characters. Joining the aforementioned green behemoth are Cyclops, Nightcrawler, Hawkeye, Magneto, Venom, Sabretooth and Doctor Doom. Each character comes with new signature powers, skins, dialogue and conversations. And yes, 10 new Achievements are being added, bringing Ultimate Alliance's total to a whopping 60 possible Achievements.

"The signature gameplay of Marvel: Ultimate Alliance has made it a favorite among fans, as well as the best-selling Super Hero game on the Xbox 360 to date," said Rob Kostich, VP of global brand management at Activision. "By adding some of the biggest names in the Marvel Universe to the roster we're enabling Xbox 360 gamers to build a variety of all-new teams and enjoy the epic action in brand new ways."

The content does not add any new areas or villains to battle. But it adds the friggin' Hulk, so that may be reason enough for comic geeks to give the expansion pack a try. The eight characters are also being fitted to match current Marvel team bonuses already in the game. New teams are also being added to take advantage of the expanded roster.

The Ultimate Alliance DLC will be available in three separate packs. Both a Hero and a Villain Pack will be offered (containing four playable characters apiece) for 500 Microsoft Points ($6.25) each. Or you can but the Hero and Villain Pack, which includes all eight new characters for 800 Microsoft Points ($10).
